(32) And to (the people of) Madyan (Midian), We sent their brother Shu'aib. He said: "O my people! Worship Allah (Alone) and hope for (the reward of good deeds by worshipping Allah Alone, on) the last Day (i.e. the Day of Resurrection), and commit no mischief on the earth as Mufsidun (those who commit great crimes, oppressors, tyrants, mischief-makers, corrupters). [Tafsir At-Tabari]

(33) Fir'aun (Pharaoh) said: "Leave me to kill Musa (Moses), and let him call his Lord (to stop me from killing him)! I fear that he may change your religion, or that he may cause mischief to appear in the land!"
